If you need a hint, then read on! Otherwise try approaching it from a different angle.

This problem requires a bit of thinking outside the box. If you’re anything like me, then you were probably looking for a pattern. I know I was trying to see how 16 became 8 and then using that to see if it worked for the next space. But after a lot of thinking, there is no pattern that works out.

So what’s the solution?

Look at the puzzle upside-down! Then you’ll see a pattern that actually works – the new perspective is all you need! The answer is 87.
